D-ary heap array
WebFinding the height of a d-ary heap. I would like to find the height of a d-ary heap. Assuming you have an Array that starts indexing at 1 we have the following: The d children of a parent at node i are given by: d i − d + 1, d i − d + 2, … d i + 1. The height of a heap (which is slightly different than the height of a binary search tree ... WebMore generally for a generalized d-heap, the items may be viewed as the nodes in a complete d-ary tree, listed in breadth-first traversal order: the item at position 0 of the array (using zero-based numbering) forms the root of the tree, the items at positions 1 through d are its children, the next d 2 items are its grandchildren, etc.

The d-ary heap or d-heap is a priority queue data structure, a generalization of the binary heap in which the nodes have d children instead of 2. Thus, a binary heap is a 2-heap, and a ternary heap is a 3-heap. According to Tarjan and Jensen et al., d-ary heaps were invented by Donald B. Johnson in 1975. This … See more The d-ary heap consists of an array of n items, each of which has a priority associated with it.

A little algebra tells us that the number of levels required to hold n items in a d-heap is log d (n*(d - 1) + 1). So a 4-heap with 21 items takes log 4 (20*(4 - 1)+1), or 2.96 levels.
